摘要
A system and a method for a digital video broadcast are provided to add a field for storing information on sub-services to an ESG(Electronic Service Guide) fragment to use several sub-services in a selected service when a specific channel is selected, thereby supplying the sub-services as well as a main service to a user. A digital broadcast station(300) adds sub-schedule ID fields, in which information on at least one sub-service related to a main service is stored, to a service information fragment for providing information on services. Sub-schedule ID values are set for the sub-schedule ID fields to schedule ID values included in a sub-service information fragment, and then transmits ESG data including the generated sub-service information fragment. A digital broadcast receiving terminal(350) receives the ESG data, checks information on at least one sub-service related to a main service through the sub-service information fragment if the main service is selected, and displays the checked sub-services and the main service on a screen at the same time.
